(For
All
Tools)
WARNING:
WHEN USING ELECTRIC TOOLS, BASIC SAFETY
PRECAUTIONS SHOULD ALWAYS
BE
FOLLOWED TO REDUCE
THE RISK
OF
FIRE, ELECTRIC SHOCK, AND PERSONAL
INJURY, INCLUDING THE FOLLOWING:
READ
ALL
INSTRUCTIONS.
1.
KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
2.
CONSIDER WORK AREA ENVIRONMENT. Don't use power tools
in
damp
or wet locations. Keep work area well
lit.
Don't expose power tools to rain.
Don't use tool
in
presence of flammable liquids or gases.
3.
KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool
or
extension cord.
4.
STORE IDLE TOOLS. When not
in
use,
tools
should be stored
in
dry, and high
or locked-up place
-
out of reach of children.
5.
DON'T FORCE TOOL.
It
will
do the job better and safer at the rate for which
it
was intended.
6.
USE RIGHT TOOL. Don't force small tool or attachment to do the job of a
heavy-duty tool. Don't use tool for purpose not intended; for example, don't
use circular saw for cutting tree limbs or logs.
7.
DRESS PROPERLY. Don't wear loose clothing
or
jewelry. They can be caught
in
moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering to contain long hair.
8.
USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
9.
DON'T ABUSE CORD. Never carry tool by cord or yank
it
to disconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
IO.
SECURE WORK. Use clamps or a vise to hold work. It's safer than using
your hand and
it
frees both hands to operate tool.
11.
DON'T OVERREACH. Keep proper footing and balance at
all
times.
12.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing acces-
sories. Inspect tool cords periodically and if damaged, have repaired by
authorized service facility. Inspect extension cords periodically and replace
if damaged. Keep handles dry, clean,
and
free from oil and grease.
13.
DISCONNECT TOOLS. When not
in
use, before servicing, and when changing
accessories, such as blades, bits, cutters.
2
14.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removed from tool before turning
it
on.
15. AVOID UNINTENTIONAL STARTING. Don't carry tool with finger on switch.
Be sure switch is OFF when plugging in.
16.
EXTENSION CORDS. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry
the
current your product will draw. An undersized cord will cause a drop in
line voltage resulting in
loss
of power and overheating. Table
1
shows the
correct size to use depending on cord length and nameplate ampere rating.
If
in
doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

VOLTAGE WARNING: Before connecting the tool to a power source (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplate of the tool. A power source with voltage greater than that specified
for the tool can result
in
SERIOUS INJURY to the user
-
as well as damage to
the tool.
If
in
doubt, DO NOT PLUG IN THE TOOL. Using a power source
with
voltage less than the nameplate rating is harmful to the motor.
For all grounded tools with American type plug.
GROUNDING INSTRUCTIONS: This tool should be grounded while in use to
protect the operator from electric shock. The tool is equipped
with
a three-
conductor cord and three-prong grounding-type plug to fit the proper
grounding-type receptacle. The green (or green and yellow) conductor
in
the
cord is the grounding wire. Never connect the green (or green and yellow) wire
to a live terminal. Your
unit
is for use on
115
volts and has a plug that looks
like Fig.
"A'.
An adapter Fig.
"B"
and "C" is available for connecting Fig.
"A'
type plugs
to two-prong receptacles. The green-colored rigid ear, lug, etc., extending from
the adapter must be connected to a permanent ground, such as a properly
grounded outlet box.

ADDITIONAL SAFETY RULES
1.
Wear a hard hat (safety helmet), safety glasses and/or face shield.
It
is also
highly recommended that you wear a dust mask, ear protectors and thickly
padded gloves.
2.
Be sure the bit is secured
in
place before operation.
3.
Under normal operation, the tool is designed to produce vibration. The screws
can come loose easily, causing a breakdown or accident. Check tightness
of screws carefully before operation.
4.
In cold weather or when the tool has not been used for a long time, let the
tool warm up for several minutes by operating
it
under no load. This will
loos-
en up the lubrication. Without proper warm-up, hammering operation is
difficult.
Be sure no one
is
below when using the tool in high locations.
5.
Always be sure
you
have a firm footing.
6.
Hold the tool firmly with both hands.
7.
Keep hands away from moving parts.
8.
Do
not leave
the
tool running. Operate the tool only when hand-held.
9.
Do
not point the tool at any one in the area when operating. The bit could
fly out and injure someone seriously.
IO.
When drilling or chipping into walls, floors or wherever "live" electrical wires
may be encountered,
DO
NOT TOUCH ANY METAL PARTS
OF
THE TOOL!
Hold the tool by the insulated grasping surfaces to prevent electric shock
if
you drill or chip into a "live" wire.
11.
Do
not touch the bit or parts close to the bit immediately after operation;
they may be extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
5
Bit grease
Coat the bit shank head beforehand with
a
small amount (about 0.5-
1
g;
0.02-0.04
oz.)
of bit grease. This chuck lubrication assures smooth action and longer service life.
